Bursting control sending one file to printer instead of multiple files

I have copied the bursting control file below. While running I am giving concurrent request that has data for 4 employees in it. I am expecting the below control file to split the output into 4 files and send it to the printer with file name as employee name. But it is sending only one file with the filename as unknown.
